iMPROVEMENT lN PENS.

The ScheduIe referred to iu these Letters Patent and making part of thesame.

II, GnnMoNn CaANonnL, ot' thecity and county ot \Vashmgton,' in DtheDistrict ot' Columbia, have invented certain Improvements inWriting-Pens, ot'

which the following is a specification.

The tirst part oi" my invention relates -to the construction of the nib7in such a way as to give increased .depth at the extreme point, toprevent catching on making the upward stroke; also, in constructing thetwo sections of the nib in such a way as closely to resemble the bladesof a drawing or ruling-pen, thereby securing a perfect-ly smooth line in'the downward stroke.

The second partof my invention relates to the combination of my pen withamovable slide on the top of the pen, by moving which, toward the point,prevents or regulates the flexibility' of the nih, so that it may beused as adrawing-pen, making any desirable width of line.

Figure 1 is a plan view ot' a pen embodying my invention.

Figure 2 is a top view of the same after beine,r formed. M

Figure 3 is a side elevation otA the saine.

Figure 4 is a side elevation with a section removed,

disclosing the loop for holding the ink.

Figure 5 is aside elevation, showing the movable slide h for regulatingthe flexibility.

.For the shape of the body of the pen, any ot the known forms may beused.

Fig. l represents a dat piece ot' metal as rst eut with the dies.

0n bending the bodyot' the pen in its proper shape, the open space c isclosed, the two sections of the nib being tirst twisted or heut inwardin the direction ot' the dotted lines c d, as shown in fig. .t; thisvbrings the two flatsuri'aces together at the point (l, and cmistitutesthe split for the flow oi' the ink.

Should the rounding of the pen fail to close the opening c, a littlebend downward, at the point where the dotted line (t 71 crosses, willeii'ect-ually do In the construction ot' metallic pens, heretofore, fortine writing, it was found indespensable to grind each side down untilthey nearly came to au edge at the point; then, in order to get theproper iexibility, the metal ot' which the pcn was made must also beveryrthin, so that the point ot' the pen when finished wasnecessarily!sharp, almost like a needle.

Vith such a point it was almost impossible to make the up stroke withoutone foot of the nih catching and' spatterng the ink, or the entire pointpenetrating the paper.

The object of my iuvention is to overcome this difficulty, and also tosecure a perfectly smooth line, on both edges, in the down stroke. This,I believe, I have effectually accomplished.

By cutting each halt` of the nib broader at the point, at first, andthen turning it up edgewise perpendicular to the body of the pen, Isecure any desirable depth of point up and down, and consequently cancttectuall y prevent any catching and sputtering o'i' ink, and thepossibility of penetrating the paper inl mkaing the up stroke, at thesame time securing the line hair line desired.

.By this arrangement of nib, I also secure a Very important feature ofthe drawing-pen, the two edges corresponding to the blades of thatinstrument, and, like them, in making the down stroke, each side ot' thenib makes a slightly indented track or channel, by means ot' which theink is guided, and a perfectly smooth line obtained.

When the point is made ot' the same material as the pen, these edges areformed by turning each section of the nib up edgewise, as stated.

But when extra pieces are added, as in the gold peil, these pieces areto be worked down to au edge on the under part, from the point back, tothe same sharpness as at the cxtreme point, so that, ou pressing the peudown for a broader mark, the same thiu edges will he kept on the paper,instead of the const-antly-ncreasiug width from the point back, as iuthe present plan.

By means ot' the slide h moving under the loop g, or its equivalent,fig. 5, this pen becomes a very good substitute for the drawing-peu.

Wheli moved forward, as shown in the ligure, it

prevents the spreading of the two parts of the nih,

and therefore secures a tine, even, hair mark.

.By moving the slide a little back, a slight motioi.` is allowed thenib, the sect-ions opening slightly, and consequently a larger line isobtained.

Any desirable size ot' line may be secured in that way, by moving theslide back or forward.

Fig. Lt represents the loop or strap f, secured to the body ot' the penand extending well toward the point on the under side, for the purposeof holding a larger quantity oi' ink than the pen would otherwise carry.l

This lnay be att-ached tothe pen, as shown in the fi gurc, or fastenedto the pen-hoh'ler, as desired.

I claim as my inventionl. Increasing the depth of the nib of ordinaryelastic metallic pens, when such increased depth is produced by formingedges ou thc under ,parts of the nib, running back from the point towardthe heel of the pen, substantially as and for the purposes set forth.

2. The improved pen, as described, in combination with the slide 71,01'its equivalent, substantially as and for the purposes specified.
